Description

Tidal power generating device

Technical field

The utility model relates to a kind of electricity generating device that fully utilizes buoyancy and gravity, belongs to energy field, especially a kind of tidal power generating device that utilizes the marine energy generating.

Background technique

Electric power energy, a kind of indispensable resource as current social progress and economic development is having a strong impact on worker, agricultural production and daily life, and is especially coastal than developed regions.And present topmost forms of electricity generation is thermal power generation, is a kind of forms of electricity generation that converts electric energy by recovery of subterranean colliery, oil, rock gas to.Though this forms of electricity generation can be alleviated the electricity needs that increases day by day to a certain extent, but a large amount of recovery of subterranean resources will certainly be destroyed geologic structure, cause surface depression, waste residue, the waste gas of thermal power generation have simultaneously directly polluted atmosphere and physical environment, are threatening that people's is healthy.Therefore, can solve serious day by day electrical problems purpose free from environmental pollution again in order to reach, experts and scholars both domestic and external are constantly seeking new energy replacement thermal power generation, such as: hydroelectric power, nuclear power, solar electrical energy generation, wind-power electricity generation, seawave power generation, tide generating or the like.

But hydroelectric power addressing condition harshness will be paid covered costs such as village, good farmland, cultural relics and historic sites, and the mud of while reservoir area, the bottom that drift sand can make the reservoir area raise, water capacity reduces hydroelectric effect of serious threat and life time.If the contradiction at rainfall rate I haven't seen you for ages aggravation industrial or agricultural, civilian etc. and hydroelectric power station contention water source; The solar electrical energy generation floor space is big, because of night and overcast and rainy influence are difficult to realize the continuity generating; Wind-power electricity generation and seawave power generation are strong excessively to the wind-force dependence, and are difficult to avoid high wind to destroy and the abnormal problem of breeze wind, and the fusing of morning and evening tides and wind-force, wind direction is indefinite etc. has increased how insoluble factor to seawave power generation.Tide generating is to use for reference hydroelectric drop pressure principle basically, because of sea rising tide, full sea, ebb tide and buy unmodifiable regular influence such as tide, makes its continuity generating dutation weak point.Also have another problem be exactly hydroelectric turbine long period of soaking in water, the corrosion of the accessory of seriously corroded, particularly seawave power generation and tide generating is more outstanding.

Above-mentioned various forms of electricity generation are owing to all exist the influence of self shortcoming and external factor, so fail to replace thermal power generation so far.

Summary of the invention
